Phylogeny and Spatio-Temporal Diversification of Prunus Section Mesopygeum

Dryad data supports a phylogenetic study of Prunus subgenus Laurocerasus section Mesopygeum in the Malesian region. The analysis uses nuclear ITS and ETS and plastid psbA-trnH, rps16, rpl16, and trnC-petN sequences to reconstruct evolutionary history. It estimates the section originated in continental Asia around 44.71 Mya and infers nine dispersal events between major geographic areas.

Use Cases

• Reconstruct the phylogeny of Prunus section Mesopygeum using nuclear ITS and ETS and plastid psbA-trnH, rps16, rpl16, and trnC-petN sequence data.
• Estimate divergence times and ancestral geographic areas to model spatio-temporal diversification across the Sunda and Sahul shelves.
• Analyze inferred dispersal events, such as mid-Oligocene movements from continental Asia to the Sunda shelf, in relation to Neogene geologic events.

Strengths

• Phylogenetic analysis is based on multiple genetic markers: nuclear ITS and ETS and plastid psbA-trnH, rps16, rpl16, and trnC-petN sequences.
• Provides a concrete estimated origin time for the section of c. 44.71 Mya (95% HPD: 31.66–46.90).
• Identifies four main subclades and infers nine specific dispersal events between major geographic areas like the Sunda and Sahul shelves.

Limitations

• The dataset's underlying structure, including row count, column names, and file formats, is unknown, limiting immediate analytical use.
• As a phylogenetic study, the data may be highly specialized for evolutionary biology and not readily applicable to other fields without significant domain expertise.
